Planted several in my Seattle WA parking strip, about 18" on center in groups of one, two, or three. If planted carefully so they're not below the surrounding soil, but with a low watering well, & not flooded w/ water, they grow beautifully & retain their multi-colored blades all year. Flower stalks fountain & droop. i remove these by simply combing thru the grass w/ my bare fingers, pulling gently. I've never in 5 years cut them back. In spring I pull out any dead blades around the base of each plant. I'll be planting more in my front garden to tie it to the parking strip. Looks beautiful w/ Lavender 'Hidcote' & Heuchera 'Midnight Rose' or 'Obsidian'.
